Hi and thank for your quick answer I am learning fast in this forum. Ok I solved the problem already, the main problem was Winrar confiration when you install the latest version by default he put ISO files in rar format, so I only need to uncheck this option and burn my disc with Nero without any problem.
I used Knoppix and it a cool distro for a newbie like me....hands down everything is working perfectly but I have a problem with my ADSL modem because Knoppixx didn´t find my moden, I have a Zyxel Prestige 630 Series and I was lloking for some driver but I didn´t find anything, in order to install Mandrake 10 I need to practice in Knoppix and now I am worried than MDK didn´t recognice my ADSL Modem also.
Anyone here have this modem here? Where I can find the drivers for Linux?
